Hi @miketeo2000, thanks for reporting this 🙂 it’s quite possible that this issue hasn’t been reported before. Could you please file an issue on [GitHub - ember-learn/ember-api-docs: Ember API Docs viewer](http://github.com/ember-learn/ember-api-docs) for the api pages & [GitHub - emberjs/website: Source for emberjs.com](https://github.com/emberjs/website) for the other one? ---

Would you post some screenshots about the website issues too? I have Windows 7 and IE11 and cannot reproduce these issues. ![issue-emberdotcom-ie11](https://us1.discourse-cdn.com/flex019/uploads/emberjs_public/original/2X/1/1139e22dd75ffb52fc8eef8f858da17733c5ce4b.JPG) ---

Hi, the blog page will result in ‘Symbol is not defined’ error if you have the developer tools open. I have raised issue [#3253](https://github.com/emberjs/website/issues/3253) on github’s emberjs/website. ---

Hi All, I too am having the same problem. Most of the pages seem to work but the API pages never load for me ( tough going considering I’m writing a Ember prototype at the moment ) Unfortunately I don’t have access to another browser on this machine. I will update the GitHub ticket [#3253](https://github.com/emberjs/website/issues/3253) as well . ![IE11-API](https://us1.discourse-cdn.com/flex019/uploads/emberjs_public/original/2X/d/d1656991ad17fc4c5cd432513f799aae860dc95b.png) ---

@terminalpunk - That seems like a different issue than the one reported in ['Symbol' is undefined error on IE11 (Windows 7) · Issue #3253 · emberjs/website · GitHub](https://github.com/emberjs/website/issues/3253). I opened [Cannot navigate left nav links in IE11 · Issue #482 · ember-learn/ember-api-docs · GitHub](https://github.com/ember-learn/ember-api-docs/issues/482) to track that down…
